/**
 * One hot summer day Pete and his friend Billy decided to buy a watermelon. 
 * They chose the biggest and the ripest one, in their opinion. 
 * After that the watermelon was weighed, and the scales showed w kilos. 
 * They rushed home, dying of thirst, and decided to divide the berry, 
 * however they faced a hard problem.

 * Pete and Billy are great fans of even numbers, 
 * that's why they want to divide the watermelon in such a way that each of 
 * the two parts weighs even number of kilos, at the same time it is not obligatory 
 * that the parts are equal. The boys are extremely tired and want to start their meal 
 * as soon as possible, that's why you should help them and find out, 
 * if they can divide the watermelon in the way they want. 
 * For sure, each of them should get a part of positive weight.
